What's up with that? Hotmail reports alot of failures with RFC822 5.0.0 and no such RFC exists. Any clues? I'm trying to trouble-shoot something. MS doing its own thing again?

In case you don't know what an RFC is, it stands for "Request for Comments." This is kind of a misnomer, since RFCs are usually published in their final form. Since the early days of the Internet, when Al Gore was tinkering in his garage, every protocol or standard ever used on the Internet can be found in an RFC. It's all there if you know where to look. Want to know why Email addresses use the @ symbol? It's in an RFC somewhere. Want to write an FTP client? Look up the RFC. It's hours of fun reading.

Anyway, RFC822 is a famous one, first written in 1982 (and kids today think Email is something new!). It defines the mail header for messages. Every mail message ever sent over the Internet uses RFC822.

The 5.0.0 is probably what is described in RFC1893, a fairly recent addition, titled "Enhanced Mail System Status Codes." 5.0.0 = "Permanent Failure, Other or Undefined Status." In other words, they don't have any idea, but it's bad, and there's no work around. Typically it ends up being something as simple as a downed server.

Except the part about Al Gore. He invented the internet in a secret labratory in the basement of CIA headquarters, not in his garage. Duh!

Anyway, 1893 is the correct RFC. Thanks!
and the year it was really invented - nmfiltersweep
